A field-mapping and crystal-chemical study of two aluniteand halloysite-rich deposits in the Turplu area, situated northwest of Balıkesir on the Biga Peninsula of northwest Turkey reveals a mineralogically diverse and a potentially economic clay deposit. The mineral assemblage along fault zones is dominated by halloysite and sometimes alunite. The alunite is nearly end-member in composition (a ...

Genetic engineering is a powerful means of accclcrating the evolution of new biological activities and has coDsiderable potential for constructing microorganisms that can degrade environmental poUutants. Critical enzymes from five different catabolic pathways of three distinct soil bacteria have been combined in patq,.work fashion into a functional ortbo cleavage route for the degradation of me...

This paper explores the utility of assemblage theory for intergenerational counter-mapping and, through this, for reconfigurations of indigeneity. Counter-mapping is theorised as a kind of assemblage that, through intergenerational learning, is fundamentally memetic (composed of evolving units of information) in nature. Assemblage is theorised as having three aspects (relations of exteriority, ...

Twenty-three trilobite taxa are described here from the Early Ordovician (Tremadocian to Floian) Nambeet Formation retrieved Barnicarndy 1 drillcore, Canning Basin, Western Australia. This includes one new genus, Veeversaspis gen. nov., and six species: Asaphellus zheni sp. Madiganaspis lauriei Norasaphus (Norasaphus) jagoi Rodingaia leggi Sanbernardaspis excalibur jelli et nov. fauna can be di...

a r t i c l e i n f o Soil represents the largest reservoir of terrestrial organic C, and plays a critical role in global C cycling. In light of predicted climate change and a more unified approach to mitigate greenhouse gas emissions, the soil's ability to sequester C, and thus to act as a sink or a source for atmospheric CO 2 has received growing interest. Organomineral assemblages are a uniq...

Two major genotypic assemblages of Giardia intestinalis infect humans; the nested real-time polymerase chain reaction (PCR) was used for targeting the triose phosphate isomerase (tpi) gene to detect and genotype G. intestinalis in human feces in Egypt. Among 97 fecal samples, 30 (31%) were diagnosed as giardiasis by saline wet mount microscopy after staining with Lugol's iodine. The tpi gene wa...
